Whales' Ingenious Use of Kelp: Playful Toys and Antibacterial Shields

Researchers have observed over 100 whales, including humpback, gray, southern, and northern right whales, playing with kelp and seaweed, a behavior known as "kelping." Using drone footage and social media posts, scientists have discovered that kelping is a global phenomenon. The whales engage in this behavior for fun and because it feels good on their skin. Kelp also helps whales get rid of hitchhikers like barnacles and lice, as its rough surface can brush them off and its antibacterial properties reduce bacterial growth. Kelping is also a social activity that enhances social bonds and aids learning among whales.
